v Application filed February 28, 1898. A Serial No. 672,068. (No model.)

T @ZZ wwnt t may concern:

Be it known that I, BENJAMIN F. DOUGLAS, a citizen of the United States, residing at Mount Union, in the county of Huntingdon and State of Pennsylvania, have invented certain new and useful Improvements in Grave- Vaults; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains tomake and use thev same, reference being had tothe accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to no vel and useful im' A further object of my invention is to provide a vault that will be simple inconstruction and cheap to manufacture and one that will render the vault absolutely air and Water tight. f

Theinvention consists in the improved construction hereinafter fully described, and de-` iined in the appended claims.

In the accompanying drawings, forming a part of this specification, Figure 1 is a-perspective View of the vault complete. Fig. 2 is a section taken on line .fr of Fig. l. Fig. 3 is a transverse vertical section of the vault with the cover in place. Fig. 4 is a plan View of the bottom of the vault, looking at the upper side thereof. Fig. 5 is a transverse-section of the bottom, taken on the line y y of Fig. 4.

Referring to the drawings, the numeral 1 denotes the bottom of the vault, which in car.

rying out my invention Iprovide with intersecting side grooves 2 and similar end grooves 3, so made as to form shoulders 4 and dovetail grooves 4', upon which shoulders the tongues 5 of thejside sections 6 are adapted to rest when the sections are assembled, thus bringing the corresponding dovetail vgrooves of the cover 16, are adapted'to rest.

7 in the lower edges of the sidev section 6 and the end sections 8 immediately above the groove 4 in the bottom section and in position to receive the molten metal as the same is poured in the vertical openings 9, which openings'are in the shape of a double dovetail, which is formed by the vertical dovetail' Referring particularly to Fig. 3 of the draW- ings, it will be seen that the upper edges of the side and end sections 6 and 8 are grooved to form shoulders 13 and inclined inner sides 14, upon which shoulders the horizontallyextending flanges 15, formed at the lower edge Ipreferably groove the edges of the cover in such amanner that the flange 17, extending ,enf

tirely around4 said cover, will beformed at its upper edge with a sufficient space between vthe said lianges'17 and the inner sides of the side and end grooves 2 and 3, soif in sealing the vault it is found that the metal has not entirely filled the vertical and horizontal grooves a sufficient quantity of metal to complete the sealing can be readily introduced between the bottomrand side, and end sections through said apertures, and-thus effectually seal the lower portion of the vault..

It will be understood that when the parts are assembled the dovetail portions of the several grooves of the bottom, side, andend portions will communicate and thus render it possible to accomplish a complete sealing of the side and end sectionsby.introducing the molten 'metal into said grooves through the vertical openings 9,`and the said metal willtlow freely into said grooves and close every fissure or crevice and harden therein, thus producing by the peculiar double dovetail lock a means that will absolutely prevent the parts separating and produce air and water tight joints.

In constructing the vault the side and end sections are pnt in proper position in the grooves in the bottom section, when the side and end slabs are temporarily bound together by a rope or other suitable means to insure close joints. The molten metal is then poured into the vertical openings in the corners of the vault and allowed to harden. The cover is then put in place, and a sufficient quantity of the metal in its molten state is poured into the space between the upper and inner edges of the side and end sections and the ange 17 of the top or cover, thus iirmly and hermetically sealing the cover to the vault proper.

IIaving thus described my invention, I claim- 1. A grave-vault consisting of a base or bottom formed on its upper surface with a channel which extends around the sides and ends thereof, the bottom of said channel being formed with a continuous dovetail groove e', in combination with side and end sections, the lower ends of which fit within and are supported by the walls of the channel in the base, and the lower edges of which are formed with dovetail grooves registering with the groove t' in the channel of the base, the vertical meeting edges of said side and end sections being also formed with cooperating oppositely-disposed dovetail grooves which communicate at their lower ends with the groove -t in tho base, whereby each corner of the structure is provided with a vertical fillingopening, through which molten metal is supplied to the continuous double dovetail groove between the base and the lower edges of the side and end sections, substantially as described.

2. The combination with the grooved bottom, of the sides', and ends, grooved at their edges, to cooperate with the groove in the bottoni, and having vertical grooves communieating with the bottom groove, said sides having supplemental filling-grooves near their lower edges also communicating with the bottom groove.

In testimony whereof I afix my signature in presence of two witnesses.

BENJAMIN I?. DOUGLAS.
